Carbohydrate composition and theoretical ethanol yield of rice straw. Source: Adapted
from Biomass Feedstock Composition and Property Database, Zhu et al. (2005).
Cellulose 38.6%
Hemicellulose 19.7%
Theoretical ethanol yield (L/kg dry) 0.42
Theoretical ethanol yield (gal/MT dry) 110
It is assumed that the hemicellulose fractions are all polymers of xylose.
